Principia

The lobby of the Oregon Convention Center was open to the public and between the visitors of the HydroVision International 2019 conference we walked through the corridor of the entrance on the Martin Luther King Jr. Boulevard to the entrance on Holladay Street.
We walked thereby underneath the two sky-lit glass spires that dominated my previous posts.

In and under one of the two towers is the artwork "Principia" by New York artists Kristin Jones and Andrew Ginzel.

Principia consists of three parts.
In the sky-lit glass spire a massive 430 kg heavy, 91 cm diameter brass spherical Foucault pendulum swings on a 21 m long cable from a point high in the glass spire. (picture 3)
Suspended horizontally, just below the pendulum, a 40 foot diameter gilt crown or slim gilt tapers hovers, providing visual reference to the rotation of the floor, building, and earth. (picture 2)
The floor is a terrazzo roundel of richly pigmented ultramarine blue and Pompeian red matrix, inlaid with blue and clear glass cullet.
Used materials: Brass, Stainless Steel, Steel, Stone, Epoxy terrazzo, Fiberglass, Mechanisms, Gold.

“In a building forever in flux, Principia‘s Foucault pendulum reveals the eternal invisible forces so omniscient and yet not readily apparent in a structure dedicated to the moment. The observer is propelled to contemplate ones relative position between stasis and eternity.” (website Kristin Jones and Andrew Ginzel)
